Re: Hotmail hacked?
It defies common sense that user side machines are being compromised for hotmail credentials. We see phishing activity to get student and faculty authentication data, and then the compromised accounts are used for spamming. It isn't the user machine being compromised in that case, but it also isn't the server being compromised.
I assume that the same kind of phishing activity goes on with hotmail, yahoo, gmail and similar services.
Incidentally, the phish mails I have seen for this typically ask for a response by email, so they don't contain any phish url that could be listed with »/phishtrack

Dear firend,
Hello.How are you doing recently?Some days ago, I came across a wonderful
electronic company on the web and had a pleasant chat with the sales manager who
can offer various kinds of digital products,such as the phone s, T V, noteboo
k, video, computers, Mp 4, GP S,PS 3, digital cameras and so on. He told me that
they are planning to lower the prices greatly in order to adapt to the global
economic crisis, so that they can expand their overseas market! I have bought a
computer,and i am very satisfied with their items and services.If you have
time,you can have a look.
Their website: sell-good.com
Their Email: sellgood@188.com
Their Msn: sell-good@msn.com
Do a search on "sell-good.com", or check these:

Hotmail has a problem and they seem to refuse to acknowledge it.

1 edit | said by madylarian :..... Hotmail has a problem and they seem to refuse to acknowledge it. mady That identical issue has also been occurring with Yahoo accounts. Complaints about the Hotmail hijacking go back to at least the third quarter of 2008, with the identical scenario. The spam is always for domains registered in China, selling cheap counterfeit knock offs of everything from clothing to electronics.
You can see pages of reports of the identical spam with the same format of missing spaces in the text: »www.google.com/search?hl=en&q=%2···erful%22
Without the forced quotations more are pulled in: »www.google.com/search?hl=en&q=He···aq=f&oq=
I agree that it is most likely not a phishing issue, possibly related to session cookie hijacking, or some other flaw. The interesting fact is that many victims passwords are not changed, so I presume we can rule out some form of account resetting. Many victims also report that their account now contains an embedded signature of the spam that is sent along with every out bound mail that the victim subsequently processes.
I read you other forum post: »windowslivehelp.com/community/t/22022.aspx and if I understand it correctly, your password was not changed, though you are unable to change it now? Also, you said that the outbound spam mail does not show in your sent items? You don't by chance have a copy from one of the people in your address book, so that you can see from the headers what the originating IP was.?
I believe that there was a recent report in this forum about the identical issue, maybe several posts.
Here is a report from that above Google link from circa 12/2008: »www.hisstank.com/forum/general-d···unt.html
I also think that there could be a scripting exploit on Hotmail's servers, see these peculiar reports for example: »scoundrelpublishing.com/spart/vi···c93a748d
All have the common modus operandi though, batches of out bound mail to address contacts, all spamming the same type of Chinese domains.
In fact the one you listed sell-good.com is hosted on a server in China with other domains that also show up in victim reports:
Search Results for 58.30.225.41 [no reverse DNS set]
10 Results for 58.30.225.41 (Sell-good.com)

07. Elebc.com

Many seem to rotate between two DNS servers:

History:
2009-01-15 Transfer FROM 53dns.com TO 71one.com
2009-04-22 Transfer FROM 71one.com TO 53dns.com
A check of sites using the 53dns is inconclusive:
»www.gwebtools.com/ns-spy/dns1.53dns.com
Agree with SnowyOne I think Hotmail is missing the ball with that boiler plate response. There is something else at work here, and it may involve direct scripting exploits at their end, or insecure session cookies that can be hijacked.
Live Help has been sprouting that same secure your account response since back in December of 2008: »windowslivehelp.com/community/p/···024.aspx However there are enough reports from people who do not appear to have compromised PCs, or were phished. That earlier link has one victim who had all three of his hotmail accounts compromised simultaneoulsy.

Selling knock off Apple products from China too, in 2008 many of these fake clones ended up on Ebay, all were useless junk.
Nice, anytime you see VISA and MASTERCARD logos alongside a WESTERN UNION logo, that means that they never accept credit card payments, only cash via WU. WU logos over rule all others, and will be the only form of payment accepted.
Lots of Flash, plus online chat, may not show up in siteshots:

I suppose it wouldn't be too difficult to query a few hundred thousand hotmail accounts in a day using one less login attempt than would trigger an account lockout with hotmail, or anyone else. |

| Yes, they could run consecutive scripts after a wait time from multiple IPs and over time go through a load of passwords. I am not sure what the account lock out settings are for Hotmail.
They can also accrue the contacts in each account to provide a never ending pool of addresses. nwrickert 's phishing scenario is also valid, as I am sure they are not limiting themselves to a single vector. The issue for Live Help though is that there are such a wide range of victims that their error is just assuming that every compromised account report equals a victim who was conned out of their password or has an infected machine.
Many of the reports also describe an after effect of a malfunctioning account. Presumably the operation of sending spam to batches of a half dozen addresses at a time, and the addition of a spam signature is also a scripted event.
Though there are a considerable amount of similar reports over a long period, I do not see any reports of the known method of compromise, or detailed analysis. Clearly though, the purpose is identical, and the accounts appear "borrowed".

MGD: I was finally able to change my password. I guess I should have known that Hotmail doesn't play nice with Firefox.
To answer your other questions, I did see those other threads and there was nothing in my sent folder, no signature (I don't think I ever made one), no vacation response, and no embedded spamvertising other than that added by Hotmail.
And, as a matter of fact, I DO have one of the emails, including headers, from someone in my contact list. They are the person who told me this had happened. I'll post the headers below, but with email addresses redacted. FYI, I am on Comcast as is the recipient of this spam.

However I like to see the "X-Originating-IP" show up again in the first received line. This would be preferable, where the X-originating also repeats in the first line:

X-Sender: anyname@hotmail.com
Though in your case the foreign originating IP is substantiated by the fact that the mail is not in your sent box, which it would not be if it originated from IP 124.135.246.67 and was also sent sent via a script and not by going through an actual webmail login. So in your case your account credentials were used fom an IP in CHINA.
I wonder if there are other victims who do see the spam in sent items, or if they are all just reporting bounces.

The password was 4 letters plus 4 numbers. The letters didn't spell anything, were not scrambled letters of a word, not in alpha order and not in any proximity on a keyboard. The numbers also were not in any particular order.

I am presuming that line above does not mean that it was a true SMTP, like from an smtp client. My outbound hotmail sent via an SMTP client will not show in my "webmail" sent items. However in madylarian 's case they had to at least log in via webmail in order to hijack her address book.

Interesting...
Do you routinely stay logged in to MSN while browsing the web, or is it set to auto log in. I am wondering how the MSN session id cookie behaves.
I know in the past a proof of concept with Gmail for example allowed a session login cookie to be hijacked and then used from another IP, though it was a complex process, that would appear to be way above this skill level.
I like SnowyOne 's potential scenario, there is an abundant supply of cheap labor There could be thousands gainfully employed testing pws 21/7.
124.135.246.67 does not show up on any listings, so I assume they are not spewing from that IP. Not a ptr on any IP in the route as soon as you hot the mainland:

I only check Hotmail (and my other junk accounts) once a day. I close the window but I don't log out. However I did let Firefox save the password, so I am not sure if that is what you mean about auto log in. That is, when I go back the next day I don't have to log on again. Is that what you mean?

Just curious why you might think that 'Microsoft SMTPSVC(x.x.xxxx.xxxx)' would not be a "true SMTP", like from an SMTP client? Good catch, Now that you bring it up, I am curious why I made that statement too !. It is incorrect,
'Microsoft SMTPSVC(x.x.xxxx.xxxx)' will show up in the headers regardless of whether the email originates from within a local SMTP client or is sent via the webmail interface.
As you mentioned in another post mail sent via an SMTP client will not show in the sent items of the webmail interface.
Apparently in some cases the hackers are copying the victim's address book and then spamming via a n smtp application. I am not sure if some victims are reporting that the spam does show in their webmail sent items or not. What most do report is that their accounts are altered, either set in auto respond away mode (with a copy of the spam) or a signature is added to include the spam which then appears in all subsequent outbound mail.
I am presuming based on the sheer volume of this epidemic, that this process may be somehow scripted by the scammers.
There is not a lot of feedback coming from the support people that identifies what the modus operandi is. I am sure they have to know by now. I do not believe that all the accounts are password cracked, nor do I believe that they are all phished. There is some other angle at work here.
